Inspector David Welch with the Royal Barbados Police Force said: "A man is currently in police custody assisting with the investigation in relation to the unnatural death of Brian Mulligan. This man was held on Tuesday June 17."

Police said the 28-year-old father-of-two was stabbed with what is thought to be a knife, at around 5.30am on Sunday.

On Wednesday, Mr Mulligan's family paid tribute to him.

His sister, Erica Mulligan, said: "The whole family is going to miss him terribly. Our thoughts are with Jemma [his wife] and his two children.

"The whole family is heartbroken and hope justice will be done. Brian will always be in our hearts."
